Not necessarily. According to data from our 2009 National Survey of Sexual Health and Behavior, about 30% of women ages 18 to 59 experienced difficulty with vaginal lubrication during the most recent time they had sex.
Women may feel on the dry side for a variety of reasons. They may actually be producing little vaginal lubrication as a result of menopause (even the years leading up to menopause can be linked with less lubrication). Due to lower levels of estrogen while breastfeeding, new moms and their partners often benefit from using lubricant more regularly, too. There are also reasons people reach for lube including marathon sex sessions, and tight genital fit (you may be on the large side for your partner's vagina or anus). Plus, some couples leap into sex rather than take time to build arousal through foreplay – and it's arousal/sexual excitement that's linked to lubricant production. So if you're squeezing sex in before work, before the kids wake up from their nap, or before your teenagers duck in just before curfew (or before one or both of you falls asleep from a grueling work day), it's no surprise that you might want to use a little lubricant.
Problems aside, some people just because they like the feel of wet, more slippery sex. Lubing up a partner's penis, vagina, or sex toy can be fun. Some people feel using lube makes it easier to experience orgasm. And it can make sex with condoms feel better, too, so why not?
